.SH "DESCRIPTION"
.PP

\fBglFramebufferRenderbuffer\fR
attaches a renderbuffer as one of the logical buffers of the currently bound framebuffer object\&.
\fIrenderbuffer\fR
is the name of the renderbuffer object to attach and must be either zero, or the name of an existing renderbuffer object of type
\fIrenderbuffertarget\fR\&. If
\fIrenderbuffer\fR
is not zero and if
\fBglFramebufferRenderbuffer\fR
is successful, then the renderbuffer name
\fIrenderbuffer\fR
will be used as the logical buffer identified by
\fIattachment\fR
of the framebuffer currently bound to
\fItarget\fR\&.
.PP
The value of
\fBGL_FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE\fR
for the specified attachment point is set to
\fBGL_RENDERBUFFER\fR
and the value of
\fBGL_FRAMEBUFFER_ATTACHMENT_OBJECT_NAME\fR
is set to
\fIrenderbuffer\fR\&. All other state values of the attachment point specified by
\fIattachment\fR
are set to their default values\&. No change is made to the state of the renderbuuffer object and any previous attachment to the
\fIattachment\fR
logical buffer of the framebuffer
\fItarget\fR
is broken\&.
.PP
Calling
\fBglFramebufferRenderbuffer\fR
with the renderbuffer name zero will detach the image, if any, identified by
\fIattachment\fR, in the framebuffer currently bound to
\fItarget\fR\&. All state values of the attachment point specified by attachment in the object bound to target are set to their default values\&.
.PP
Setting
\fIattachment\fR
to the value
\fBGL_DEPTH_STENCIL_ATTACHMENT\fR
is a special case causing both the depth and stencil attachments of the framebuffer object to be set to
\fIrenderbuffer\fR, which should have the base internal format
\fBGL_DEPTH_STENCIL\fR\&.
.SH "ERRORS"
.PP

\fBGL_INVALID_ENUM\fR
is generated if
\fItarget\fR
is not one of the accepted tokens\&.
.PP

\fBGL_INVALID_ENUM\fR
is generated if
\fIrenderbuffertarget\fR
is not
\fBGL_RENDERBUFFER\fR\&.
.PP

\fBGL_INVALID_OPERATION\fR
is generated if zero is bound to
\fItarget\fR\&.
